Sergio Prado e9f66ae23c mtd: s3c2410: make ecc mode configurable via platform data
Removing CONFIG_MTD_NAND_S3C2410_HWECC option and adding a ecc_mode
field in the drivers's platform data structure so it can be selectable
via platform data.

Also setting this field to NAND_ECC_SOFT in all boards using this
driver since none of them had CONFIG_MTD_NAND_S3C2410_HWECC enabled.
